5 Common Causes of a Roof Leak

5 Common Causes of a Roof Leak

A leaky roof

Very few things evoke more fear in homeowners than these three tiny words. Heck, even the sound of a single drop of water hitting the floor can send folks racing off in search of the nearest bucket. And can you really blame them? Small roofing problems have a way of quickly turning into big ones, costing you time, money, and major headaches.

A leaky roof can crop up at any time, for any number of reasons. But keep in mind, not all roof leaks are created equal. To help protect your investment—and your sanity—we’ve put together 5 common causes of the dreaded roof leak.



Age of the roof Alas, nothing escapes the hands of time, not even your roof. One of the most common reasons for a leaky roof is age. Sun, wind, rain, and falling debris—regular wear and tear on your trusty roof can cause materials to become brittle and crack over time. Getting regular roof check-ups from a roofing professional will help ensure it weathers the storm for many more years to come.



Broken or missing roof shingles

Shingles are the single most important factor that protects your roof from the elements. Strong winds can rip shingles off your roof, exposing it to rain and snow that can cause roof leaks throughout your home. After a major storm, it’s always a good idea to inspect the roof for missing or damaged shingles.



Damaged flashing

Flashing are the thin layers of metal installed under shingles and roof joints to prevent water leakage. When the flashing gets damaged or the caulk used to seal it becomes loose, rainwater can seep into your home. Regular roof maintenance, like applying tar to damaged areas or replacing broken flashing will help stop roof leaks when it snows or rains.



Clogged gutters can be a nightmare for any roof. Leaves, dirt, and other debris can slow the waterflow, causing backups that can soak through the shingles to the ceiling below. If you want to avoid a roof leak during the wet months, make sure to clean out your gutters. Don’t have the tools or the time to gut your gutters? A roofing expert will be glad to handle the dirty work for you..



Sketchy skylights

A skylight is a great addition to your home as it can open up your space and let in some natural light—unless you need an umbrella to stand under it. Heavy rains, faulty installation, and leaf blockage are common causes for your skylight to leak. If your skylight is letting in more than just the light, you’ll want to contact a roofing contractor to assess the problem..



A leaky roof is serious stuff. Before you know it, that tiny little drip can turn into a steady stream of lost cash and patience. If your roof has sprung a leak, you’d better act fast. A little roof TLC now, can go a long way later.

Shortly after moving into our new home, we contacted Landmark about doing some maintenance on the structure's 10 year old roof - moss treatment, replacing damaged shingles and faschia board, gutter cleaning, and the installation of a new ridge-vent and water diverters. David was very personable and knowledgeable, and genuinely wanted to help and deliver good value. He and his team delivered on all fronts and I wouldn't hesitate to recommend them.
